SPECIFICATION forming part of Letters Patent No. 680,011 dated August 6,1901. Applicantsfnedrbgngry a, 190i. serai No. 46.4.94. (No modem To allwhom, t may concern."

Be it known that I, HENRY A. ALLWARDT, a citizen of the UnitedStates,residing at Detroit, county of l/Vayne, State of Michigan, have inventeda certain new and useful Improvement in Soda-Water Apparat-us; and Ideclare the following to be afull, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same, reference beinghad to theaccompanying drawings,

which form a part 'of this specification.

. My invention relates to soda-Water apparatus; and the object, of myimprovement-s is to provide an approved apparatus for refilling tankswith carbonated water which shall be simple in construction, Welladapted to be used with usual apparatus for this purpose, and whichshall `utilize the residual gasesin the exhausted tanks. I accomplishthis object in the device illustrated in the accompanying drawings, inWhich- Figure 1 is an elevation of a carbonating apparatus embodyingmyinventiou,the chamber in Which the Water is mainly charged with gasbeing shown in section. Figs. 2 and 3 are sections taken at right anglesto each other through the center of the tank. Fig. et is asection of thepressure-regulating valve. Fig. 5vis an enlarged sectional view of theautomatic stop-valve, and Fig. 6 is a plan view in section of the valveand valve-seat shown in Fig. 5.

The same letter indicates the same part in each of the views.

A is a force-pump.

B is a carbonating-chamber.

C is a pipe which connects the chamber A with a source of supply ofcarbonic-acid gas under pressure.

D is a pipe by which the carbonatedwater may be allowed to flow from thechamber A. The gas is admitted through the pipe C and by suitableapparatus is kept at a certain pressure-say one hundred and eightypoundsin the chamber B. The Water is forced by the pump A into the topof the chamber B, where it is sprayed through a perforated plate toexpose it to the gas, Which it absorbs, and it gathers at the bottom ofthe chamber, so as to cover the mouth of the outlet-pipe D.

I Fig. l.

E E are tanks in which the carbonated Water is supplied to retaildealers. These tanks are of the same construction and are onlydistinguishedin the reference-letters to indicate their relativepositions, as shown in Through an aperture in the top of the tank E isfixed a plug F, which extends to near the bottom ofthe tank.

l plug F outside of said tank.

g is a passage extending through the nozzle.G and opening into a chamberHin the plug F.

' the lower end of the plug F, extending to the fis a passage openinginto the tank E at top of said plug and communicating at its upper endwith the chamber II.

h is a valve adapted to close the entrance from the chamber H to thepassage f.

I is a second passage in the plug F, extending from a point aboutquarter of the length of said plug from the top thereof, where it opensinto the tank, to the upper end of said plug, at which point it passesthrougha nozzle J.

K is a chamber formed in the upper end of the plug F, forming anenlargement of the passage I.

7c is a ball in the chamber K. This ball is prevented from closing thelower passage to the chamber K by ribs 'L' z' il, Figs. 5 and 6, but isadapted to close the upper passage to said chamber when it is raisedsuliiciently.

The pipe D, through which the carbonated Water from the chamber Bpasses, is connected to the nozzle G. A pipe L is connected to thenozzle .I and leads to a reducing-valve M, which is adapted to open topermit the passage of a fluid from the pipe L Whenever the pressure insaid pipe is greater than a certain amount less than the pressure in thechamber B say one hundred and sixty pounds. N is a pipe leading fromgtheoutletpassage of the valve M to the inlet-nozzle G' of a second plug Fof the same construction as the plug F.

n is a pressuregage on the pipe N. Other plugs, like F F', with theirconnected tanks, may be connected in the same Way, except that only onevalve similar to M or gage similar to n will be required.

R is a pipe connecting the pipe C with the pipe L. r is a stop-cock onthe pipe R.

S is a stop-cock on the pipe D.

s' is a stop-cock on the pipe N.

The operation of the above-described apparatus is as follows:y The tankscome in to be refilled with the plugs. F in them, the valves .h closed,the water withdrawn, but still filled with carbonio-acid gas at a smallpressure. One tank is connected, as above described, to the pipe D, andone or more other tanks E are connected with the first, as abovedescribed. The cock r is opened, a1- lowing the gas to How into the tankE until the pressure therein is equal to that at which the valve M isset. The cock in the pipe D is then opened, allowing the carbonatedWater to flow-into the tan-k E through the passage f. As the waterrisesinsaid tank it compresses the gas in the tank before it and absorbs apart of it. When the pressure of the vgas in the tank E exceeds onehundred and sixty pounds or the pressure to which the valve M is set,said valveopens, allowing the gas to pass byit and into the tank E. Whenthe level of the water in the tank E rises above the lower opening ofthe passage I, the water rises in said passage, carrying the ball upwardand closing the passage I by stopping the upper passage from the chamberK, whereupon the pressure in thetank rises to that of the chamber B andthe water ceases to fiow. The valve h and cocks S are now closed, thetank E removed from the pipevD, the tank E put in its place, and a thirdtank put in the place of the tank E', and the operation is repeated.

lt may be noticed that in the above-described apparatus the tankisalways tilled to the same extent-that is, to a level just above thelower end of the passage I-that all the residual gas of the tanks isutilized, that the water will always be carbonated to about the sameextent, and that very little additional apparatus is required. Of coursethe cock s is closed before removing the tank E'.

What I claim is- 1. The combination With a tank E, having a passage-wayopening toward its bottom, means lfor detachably connecting said tankwith a source .of supply of carbonated water under pressure so that saidwater may enter said tank through said passage, said tank being alsoprovided with a passage I opening into said tank near the top thereof,of a pipe L adapted to be detachably connected to said tank so as toform a continuation of the passage I, a pressurelregulatine,r valve onthe pipe L adapted to open when the pressure in said pipe is a littleless than the pressure forcing the water into the tank E, and a secondtank E detachably connected to the outlet-passage of said reducing-v'alve and adapted to replace the first-mentioned tank,substantially as described.

2. The combination with a tank E having a passage-Way opening towardvits bottom, means for detachably connecting said tank with a source ofsupply of carbonated water under pressure, so that said water may entersaid tank through said passage, said tank being also provided with apassage I opening into said tank near the top thereof and provided withapparatusadapted to permit the passage of a gas, but to close thepassage when the water fioWs therethrough, of a pipe L adapted to bedetachably connected to said tank so as to form a continuation of thepassage I, a pressure-regulating valve on the pipe L adapted to openwhen the pressure in said pipe isa little less than the pressure forcingthe Water into the tank E, and a second tank E detachably connected tothe outlet-passage of said red ucing-valve and adapted to replace therst-mentioned tan'k, substantially as described.

In testimony whereof I sign this specification in the presence of twowitnesses.
